Etymology. This specific name is derived from the type locality; noun in apposition.

Diagnosis. This new species resembles P. splendidus (Song & Zheng, 1992) in having a similarly shaped retroventral tibial apophysis, but can be recognized by: 1) the thinner, needle-shaped embolus (vs thick, nubbyshaped, cf. Fig. 59C View FIGURE 59 and fig. 3H in Kamura [2021]), and 2) the shorter, rod-like tegular apophysis (vs arc-shaped, cf. Fig. 59C View FIGURE 59 and fig. 3K in Kamura [2021]).

Description. Male (Holotype): total length 2.58, carapace 1.23 long, 1.00 wide; abdomen 1.35 long, 0.74 wide. Eye sizes and interdistances:AME 0.08, ALE 0.08, PME 0.07, PLE 0.07; AME–AME 0.04, AME–ALE 0.01, ALE– ALE 0.20, PME–PME 0.04, PME–PLE 0.03, PLE–PLE 0.26, ALE–PLE 0.06. EAW 0.37, CRW 0.49, EAW/CRW 0.76, CRW/CW 0.49. MOA 0.22 long, anterior width 0.20, posterior width 0.20. CH 0.12, CH /AME 1.50. Labium 0.13 long, 0.18 wide. Sternum 0.71 long, 0.62 wide. Leg measurements: Ⅰ 4.96 (1.27, 0.44, 1.31, 1.17, 0.77), II 3.84 (1.03, 0.38, 0.89, 0.92, 0.65), III 3.35 (0.90, 0.34, 0.72, 0.86, 0.53), IV 5.57 (1.58, 0.42, 1.32, 1.47, 0.78).

Coloration. Carapace yellow, oval, radial striae distinct, with sparse iridescent scales in dorsal view. Abdomen darker in color than carapace, with large dorsal scutum covering nearly entire abdomen and sparse iridescent scales dorsally ( Fig. 58 View FIGURE 58 ). Legs yellow.

Palp as in Figs 59–60 View FIGURE 59 View FIGURE 60 . Femoral apophysis protruding slightly, with several setae. Prolateral tibial apophysis distinct, arch-shaped. Retrolateral tibial apophysis base wide, narrowing abruptly at middle and tip digitiform; retroventral tibial apophysis nearly trapeziform. Tegulum narrower than cymbium, oval; tegular apophysis short rod-like. Sperm duct distinct, stomach-shaped, tapering from retrolateral side of tegulum to embolus. Embolus short, transverse. Conductor absent.

Female. Unknown.
